Fluids Density Calculator
The Fluid Density Calculator allows you to quickly estimate the density of a wide range of gases, liquids, and two-phase mixtures commonly encountered in oil, gas, and petrochemical industries. By selecting the fluid type and entering temperature and pressure conditions, you can obtain accurate density values essential for process calculations and equipment design.
Fluids Included in Calculator:
Acetic Acid, Acetone, Air, Ammonia, Benzene, Brine (Saturated NaCl), Butadiene, Butane, Carbon Dioxide (CO₂), Crude Oil (heavy), Crude Oil (light), Diesel, Ethane, Ethanol, Ethylene, Formic Acid, Formaldehyde, Gasoline (Petrol), Glycol (MEG/DEG/TEG), Hydrogen, Hydrogen Sulfide (H₂S), Hydrochloric Acid (HCl), Isopropanol, Jet Fuel (A-1), Kerosene, Lubricating Oil, Methane, Methanol, Nitrogen, Oxygen, Propane, Propylene, Sea Water, Sodium Hydroxide (Caustic Soda), Styrene, Sulfur Dioxide (SO₂), Sulfuric Acid (H₂SO₄), Toluene, Urea Solution, Water, Xylene (mixed)
Notes & Assumptions:
- Gas density is calculated using the Ideal Gas Law: ρ = PM/RT.
- Liquid density is estimated from standard tables and is weakly pressure-dependent.
- Two-phase density is calculated as: 1/ρmix = x/ρgas + (1−x)/ρliq, where x = vapor quality.
- Assumes equilibrium conditions and no dissolved gases in the liquid phase.
- Results are estimates; for design use, consult detailed fluid property data.
